Looks good. The general rule of thumb for the # of sig figs is to look at the original problem; whatever the LOWEST amount of sig. figs. used in the problem statement is, is what you should give your answer in.

Thanks guys We have a take home test this week and im feeling pretty good about it. I don't get the whole take home part though because were aloud to use the internet and whatever but if i have any questions ill be sure to ask.
